A Separate Peace -- John Knowles
I read this ages ago, in high school, and didn't like it. I decided to give it a second chance.
Even from the first page, I could see both why teachers use this as a high school text and why the average high school student (me) wouldn't connect with it.
It's a great book, a dark coming-of-age story about friendship and betrayal and far-reaching consequences stemming from a brief moment of rage. It's even kind of funny, in parts:
"Is that what you like best?" I said sarcastically. I said a lot of things sarcastically that summer; it was my sarcastic summer, 1942.
But I could still totally see why the teenaged Leila didn't like it. It starts slowly, and Gene's reminiscent voice isn't one that I would have identified with; it isn't the voice of a teenager, it's the voice of an adult looking back to when he was a teenager. He does shift into his teenage voice when the flashback starts, but before that, it would have been pretty tough going for the young 14-year-old version of me. I was surprised at how much of the book I remembered, though.
If you didn't like it in high school, it's totally worth another try.
